We are going to attempt to install some A/C units in our bus. We do NOT want to look into overhead units as we may try to put in a roof deck sometime in the future. We have purchased two small A/C units and we want to mount them in a way that will look decent on the outside and will not impact our space on the inside. We have come up with the idea of mounting them in a pair over one of the wheel wells in the following manner:
My drawing sucks and it certainly isn't to scale, but we have measured and there is more than enough room over the wheel well for the two units - there is even enough room if we have to put a space in between them if there is a "rib" when we start cutting.
1. We plan on putting a rectangular box made of plywood directly on the wheel well with "legs" running the length of each side to keep it on there.
2. We plan on making the box taller than the A/C units themselves, so as to leave airflow room. This will be sealed as best as possible on the inside, but open to air on the outside.
3. We will bolt the units down to the box.
4. The units are 7500 btu's each, which should be adequate.
5. When we cut the outside of the bus, we will try and use the cutout as a "door," adding hinges to protect the units from the elements when they are not being used.
We have decided to go over the wheel well because the box will be about end table height (there are couches on either side of the wheel well) and it would be a great use of underutilized space. It will also be great for cupholders for those sitting on the couches.
So as you can expect, I have a TON of questions. I would appreciate if people would answer any and all that they feel qualified to answer. Thanks in advance!
1. What is the best way to cut the metal? What ways will work that might be cheaper?
2. Is there a rib or any other structural metal rod running where we are going to cut? Like I said above, we are planning on seeing one in the middle and we plan to mount them around it.
3. Do I really need the "airflow" space above each unit?
4. Can you think of a better way to mount them?
Once again, thanks in advance!
OK, after seeing the other buses, I've decided to include a second option for your review:
Again, sorry for the drawings, they're the best I could do. This option would allow me to utilize the windows, which are obviously already cut. Any ideas or suggestions?
